POWER-TRANSMISSION APPARATUS.

Specification of Letters Patent.

Patented Mar. 18., 1913.

Application filed December 22, 1911. Serial No. 667,419.

T0 aZZ whom it may concern:

Be it known that I, EUGENE W. MOORE, a citizen of the United States,residing at Gardena, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Apparatus to beUsed in Conjunction with an Automobile or Autovehicle for the Purpose ofTransmission of Power.

This invention relates to power transmission apparatus, moreparticularly to improved apparatus adapted to derive power from thedriving wheels of auto vehicles and transmit such power to otheragencies, purposes and objects, for instance: to machinery to grindfeed, wood sawing machinery, churning and pumping machinery, and otherkinds of machinery which do not use more power than can be obtained fromsuch auto vehicle.

Objects of the invention are to provide improved apparatus of the classspecified which is simple in construction, compact in arrangement,strong and durable, adjustable to a high degree to insure efiiciency inthe operative connection of various sizes of driving wheels to theapparatus, easy and economical to install, maintain and operate, andeffective in action.

Other objects and the advantages of the invention will be apparent tothose skilled in the art from a consideration of the followingdescription of the preferred form of construction embodying it, taken inconnection with the accompanying drawings in which Figure 1 is a rearelevation of apparatus embodying the invention; Fig. 2 is a plan view ofthe same; Fig. 3 is a side elevation of the same; Fig. 4 is an elevationof the lifting jack; and Fig. 5 is a plan view of the same.

Suitable sills 2 are spaced apart and may be connected together inparallel by suitable crossbars 3 which may be secured to the sills bybolts 4:. As shown, the crossbars 3 have at one end portion thereof aplurality of openings 5 for the bolts 4 in order that the sills 2 may bereadily adjusted closer together or farther apart.

On one of the sills 2 are suitably afiixed the standards 6 havingthereon bearings 7 for the shaft 8 which has fast thereon the driving.pulleys 9 and also power pulley 10,

' and loose pulley 11. On the other of the sills 2 may be suitablyaifiired the parts 12 each having thereon upstanding ears 13 betweenwhich on pivots 14 are mounted the lower end portion of arms 15 havingon their upper endbearings 16 for the countersha-fts 11 on which aremounted pulleys 18 connected with the driving pulleys 9 by means ofbelts 19. I

The driving wheels 20 of an auto vehicle may be run onto the belts 19 bymeans of lnclined planks 21 which may extend to the rear of and besuitably connected with one of the sills 2.

In order to admitof spacing the standards 6 and arms 15 at the desireddistance apart and to adjust the tension of the belts 19, rods 22 mayhave one end portion thereof ofiset and fitted into openings in lugs 23on the standards 6 and arms 15, and they may have the other end portionthereof threaded and fitted into turnbuckles 24.

In order to exert an adjustabledownward pull on the shaft 25 to drivingwheels 20 into frictional engagement with the belts 19, a hook 26 isremovably fitted over the shaft 25 and has the lower threaded endthereof fitted in a turnbuckle 27 in which is fitted the upper threadedend of a a hook 28 which is connected to the upper end of a rod 29provided with a head 30 on its lower end adapted toengage one end of aspring 31 which spring has its other-end bearing against the upper endportion of the upstanding bracket 32 which may be adjustably afiixed bybolts 33 to one of the bars 3 having a plurality of openings 34 thereinfor the bolts 33.

The wheels 20 may be lifted into and out of position'on the belts 19' bymeans of any suitable form of jack 35, that shown in Figs. 4 and 5consisting of a head 36 adapted to fit against the axle 25 and having astem 37 which is movably mounted on the standard '38 and provided onopposite sides thereof with teeth 39 between which are adapted to fitthe pawls 40 which are pivotally mounted on the handle 4-1 which latterin turn is pivotally mounted at the upper end of the standard 38. Itwill be understood that when the handle 41 is moved in one direction oneof the pawls 10 rides over the teeth 39 and the other of the pawls 40engages with the teeth 39 and raises the head 36, and when the handle 41is moved in the other direction the other of the pawls engages with theteeth 39 and raises the head 36.

yieldingly press the iii ll claim: v

1. ln apparatus of the class specified, the combination of sills,crosspieces adjustahly connected between the sills, standards mounted onone of the sills, a power shait mounted on said standards, drivingpulleys on the shaft, parts provided with ears affixed on the other ofthe sills, arms having thelower end portions thereof arranged betweenand pivotally mounted on the ears, countershatts mounted at the upperends of the arms, pulleys on the countershafts, belts connecting thepulleys on the countershafts with the driving pulleys, turnbuekles, androds having one end thereof connected with the upper end portions of thearms and the standards and having the other end portions thereofthreaded and fitted in the turn buckles, substantially as described.

2. in apparatus of the class specified, the combination of sills,crosspieces adjustably connected between the sills, standards mounted onone of the sills, power shaft ineetaei the arms, pulleys on thecountershatts, belts connecting the pulleys on the countershafts withthe driving pulleys, turnbuckles, rods having one end thereof connectedwith the upper end portions of the arms and the standards and having theother end portions thereof threaded and fitted in the turnbuckles, andadjustable means connected with one of the crosspieces and adapted to beconnected with the shaft of the driving wheels of an auto vehicle toyielding-1y press said wheels against said belts, substantially asdescribed.
